To'aZZ whom it may concern.'

Be it known that 1,0110 BERGER, a citizen of the United States', and aresident of New York, borough of Manhattan, in the county of New Yorkand State of New York, have made and invented certain new and useful,lmprovements in Lubricators for Elevator-Guides, of which the followingis a specification. l

u My invention relates to lubricating devices for -applying and. moreparticularly to. lubricating devices of the eneral type disclosed inLetters Patent o. 1,007,422 granted to me upon the 31st day of October,11911.wherein a lubricant is applied to the guides 4by means of a wi Vermoving lin contact-therewith, and whic wiper is supplied with oil froman oil well. through or by means of a tubular oil feeding membercontaining a wick; and, among the objects ofmy invention are to provide`a having oil applying means separate from the wiper; to provide alubricatin- .device in which the upper end of the oil we l is open,asdistinguished from those covered by elements of the oil applying means;to provide a lu" bricating device in which the quantitylor amount of oilsupplied to the guidesmay be easily adjusted to suit the necessities ofany particular case; to vice which will be sim le in form, and which maybe readily 'and c eaply manufactured; and to provide such other andfurther -improvenients in and relating to lubricating devices forelevator guides as are hereinafter more specifically referred to.

Withthe objects of invention above onul merated in view, myI inventionconsists in the improved -lubiricating device for elevator guidesillustrated in the accompanying drawin and hereinafter described andclaimed, an in such variations and modifications thereof as .will beobvious to those skilled in the art lto which my invention relates.

In the drawing accompanying-and forming'a part 'of this application andwherein the preferred embodiment of my invention is illustrated: Figure1 is a view showing a section of my improved lubricating device takenupon a vertical planeindlcated by the line 1-1, Fig. 2, and illustratinghow ,the same may be secured to an element of .the elevator with whichit is used; Fig. 2 is a View showing my improved lubricating deoil toelevator guides,`

lubricatingl device rovide a lubricating de# viee in plan.; 'Fig'. 3,isa view showing a section taken vupon a transverse horizontal planeindicated by the line 3 3, Fig. 1,

looking down; Fig. et is a view showing a,

section taken upon a 'vertical plane indicated by the line 4 4., Fig, 3;Fig-5 is av fragmentary view illustrating a modified form of one oftheelements of my device; and Fig. .6 is a view showing the clampingand-support1ng means for attaching the lubricatoi` to an elevato1.-Y

Referring to the drawing the reference numeral 8f designates'a-'portionof a vertically'extending elevator portion of an elevator, to w issecured andwithin which a springI 11 is located, which spring acts to'.force ajshoe 12 toward and. keep it in contact `with `theguide, all asis common in 'elevator structures and to which" features my "invention1n no way relates. y

My improved lubricating device will be supported from the elevator so astov travel therewith by means of any'suit'able and appropriate bracketor equivalent supporting means, the vbracket `or support illustrated"guide, and 9 a ich a barrel 10` comprising' an lupwardly extending bar"13 the lower end of which rests upon and is secured to two clips 14 thelower ends of which cli-ps are curved to embracethebar-v rel 10, and theupper end of which bar is bent downward and serves'as the immediatesupport for' my im roved lubricatingdevice. My improved l'u ricatingdevice'comprises a reservoir 15 adapted. to contain .a consid erabl'equantity `of'oi'l as indicated in thev drawing, and which oil reservoir/is shown as rectangular incross-section, although the particular formor shape of the oil reservoir isy of secondary importance and is notin'- -volved in my invention. The `oil reservoir is adaptedto -supporta. swab 16 of absorbent material and awiper '17 also ofabsorbentmaterial, said elements being independent of one another andspaced a' arti as shown. rlhe swab is kept saturate or moistened withoil, and the purpose thereof is to 'l lubricant to the elevator guidewith it moves in contact', while the wiper ."ieives,N

t0 distribute the lubricant uniformly over the guides, and to scrape offexcess lubricant` and dirt should any collect upon the gui e.

The swab 16 and wiper 17 are shown as located within two recessedextending portions or extensions 18, 19 having upwardly extendingperipheral Aor side walls as shown,

. and the bottom walls of which extensions are provided each with a slotadapted to receive an elevator guide as illustrated in the .drawing Theupper: of these extensions is shown as formed integrally with the wallof theoil reservoirgl, whilev the lower is shownl as formed se aratefrom the reservoir andas secured tA ereto by a screw 20.l Either orbothof saidexten'sions may however, obviously, be formed' integrallywith Athe'reservoir 15,701' either or both of theml may -be formedseparate therefrom and secured thereto in any way. l. I

The extension 1 8 4is preferably provided withanv upwardly projectingwall or ledge 2l, of less height thanvthe side walls of and extendingaround thev 'slot formed in the bottom wall of said extension, wherebylan oil retaining spaceorpocketfis rovided in the .lower portionof saidextenslon. There is thusa considerable 'quantity'fof oil presentimmediately beneath the swab 16 when the lubricator is in us whereby theswabis kept saturated wit 'oil or suiciently moist' to secureV a propersupply of oil to the cle-l 4vatorvguide, as .it will be understood thata portion of the'swab extends downward and into the oil as best shown inFigkft. A block of felt 22 is also preferably provided with which thewiper is in contact, as shown, which block serves as an additional meansfor keepin the swab a saturatedicondi tion or su ciently moistenedwithoil to secure1 adequate lubrication ofA the elevator 'I he swababovereferred to will obviously be of alform appropriate to apply oil to theparticular form of elevator guide .to be 111-. ricated,. and Athe formof' my Invention illustrated in the drawing shows two such swabsarranged to apply 011 to opposite faces of an elevator guide. The swabsare shown as resting upon the upper end ofthe ledgev 21 and blocks offelt 22', andas held in place by plates 23 made preferably of induratedfiber, through Whic vbolts 24'ex`tend. The wiper 17 is also obviously ofvsucha formas to contact with and wipe the surface or surfaces of theelevator ide to be lubricated, asA willbe understoo and is held 1n laceWithin the extension 19 Vb means of p ate's 25, also preferably of inlurated liber, and

Oil is supplied to the swab 16 through or by means of an oil feedinmember comprising a tube within whic an absorbent material is contained,one end of which tube 'depends into, the oil within the reservoir 15 andthe other end of which extends to and vterminates adjacent the swab, sothat oil will pass along the absorbent material' and through thetube andto the swab; the absorbent vmaterial being preferably in the form of awick as shown in the drawing, and the lower end thereofextending intothe oil receptacleor pocket provided in the lower portion of theextension 18.

The tubular member above referred to is shown as Uv-shaped in form andas having a leg 28 depending into the oil-reservoir, and a second leg 29extending through a hole in the bottom wall ofthe extension 19 andterminating adjacent the swab 16. The upper end of this oil'feeding'member thus lies above lthe level of the oil in the oilreservoir, and the rends of the absorbent member or wick 30 thereofextend beyond then .lower ends of the legs, and into the oilv in the oilreservoir', and .intov the oil retaining space or pocket formed in thelower portion of the extension 18by` the .'ledge'21, as hereinbe- .foreexplained. The oil feeding member is referablyprovided Witha spring 31,the ree upper end Of-W'hich may be pressed against the wick, by meansof. a screw 32,

to thereby regulate .the quantity of oil pass ing along the wick to theswab.

My improved lubricating device is shown as provided with two separateoil feeding members, inorder to secure a more uniform and satisfactorysu ply of oil to the swabs 16, although it wil be understood that asingle oilfeeding member will supply oil to vthe oil retaining pocket atthe lower end of the extension 18 and consequently, to

both the swabs 16.

While I have shown the' oil feeding mem bers as comprising each a singletube with a single wick therein, -I prefer to make the oil feedingmembers in the manner illustrated in Fig. 5 whereinthe same is shown asmade up of a plurality of separate tubes 33, each of which contains awick 34, land which tubes collectively form a single oil feeding memberequivalent in function to one of the two oil feeding members with whichmy dcvice isshown as provided in the other iigures of the drawing Withthis form of oil feeding member a closer and more satisfactory controlof thegsupply of oil may be secured; zas, if the supply is insuliicientan additional tube may be added, while if the supply i's too profuse atube may be removed; it being understood that a plurality of these.separate tubes will benecessary in order to secure an adequate supplyof oil to the swabs in all cases, and 4that such supply may be increasedor decreased by small moaned ot and located above said swab and carried'by said reservoir; a tubular` lll-shaped oil :feeding memberfthenppe'rend of which lies above the level ot oil in said reservoir and one legof which depends thereinto, and the other leg of which member terminatesadjacent said swab; and a wick et absorbent material within said oilfeeding member and through which oil is supplied to said' swab. l
